Specification of Letters Patent.

Original application filed Qctobr so, 1908, Serial No. 460,238. 'nivided and this application filed March a,

To all whom it may concern Be it known that we, Louis FESSMANN and Gnnrninn HAMMERLE, the first a citizen of the Empire of Germany, the latter a citizen of the Empire of Austria-Hungary, residing at Augsburg, Germany, have invented a certain new and useful Improvement in Bobbin Frames or Creels for Warping Machines, of which thefollowing is a specification, reference being had therein to the accompanying drawings.

The present invention is a division of that of our application for U. S. patent for improvements in warping frames filed Oct. 30, 1908, Serial No. 460,238, upon which Letters Patent No. 1,0i3,309 were issued under date of November 5, 1912, and has reference more particularly to the construction of the creel or frame in which are employed bobbin or copsupporting means and combined yarn-guiding, clearing, and tension-devices on the order of those of the original application and of our companion divisional application filed March 6, 1912, Serial No. 681,937. I

The features of invention of the said applications and the present case are intended for use, more particularly, inconnection with mechanical warping machines, and are designed to enable yarns to be wound upon the beam of a warping machine directly from bobbins or cops taken from a spinning frame, and thereby render unnecessary the usual operations of winding from bobbins or cops upon spools, and from such spools upon a receiving beam, the use of the ordinary creel for such spools being rendered unnecessary, whereby much time and labor are saved, and much floor space is made available for other purposes. The said bobbin-supporting or cop-supporting means provides for receiving reserve supply-bobbins or cops which are grouped closely with the one from which unwinding actually is proceeding at any given moment, which enables the inner end of the yarn or thread on the latter bobbin or cop to be joined, as by tying, to the outer end of that of a second bobbin or cop, and so on throughout the group, so that when the yarn or thread of one bobbin or cop becomes completely unwound the unwinding will immediately continue from the next bobbin or cop in turn, and so that fresh bobbins or cops may be supplied as soon as the previous ones have Serial No. 682,408.

become exhausted, the unwinding operation thereby proceeding continuously and without interruption. Thereby the waste port ons of yarn which in the case of other methods of unwinding have had to be left on the warping-bobbins are also obviated.

V The features of the present invention are illustrated in the accompanying drawings, which also showthe bobbin or cop-supporting means and combined yarn-guiding, clearing, and tension-devices of the applications aforesaid.

In the drawings, Figure 1 shows in side elevation a bobbin-frame or creel of improved construction embodying the inven tion, with the said bobbin or cop-supporting means and yarn-guiding, etc., devices applied thereto. Fig. 2 is a plan view thereof. Fig. 3 is a view in vertical. section on an enlarged scale. Fig. a is a plan 'view, also on an enlarged scale, showing certain details of construction more clearly than in Figs. 1 and 2. I

The bobbin-frame or creel is made with two sides, each supporting bobbins or cops. These sides converge toward each other in the direction ofone end of the frame. Each side is composed of longitudinally extending horizontal rails a, a, in the form of channel-bars, (see Figs. 3, 4,) and uprights Z), Z). The said rails orchannel-bars are supported vertically one above another upon the said uprights. The arrangement of the horizontal rails or channel-bars and uprights is such as to producein each side of the warping-frame or creel a number of compartments. As shown in Fig. 1, also, a plurality of bobbin or cop-carriers is contained within each such compartment. The two sides of the warping-frame or creel are joined together and the whole stiffened by cross-pieces b, b, Fig. 2. At cl, (Z, Fig. 2 are vertical glass rods (omitted from Fig. 1) carried by outstanding supports d extending from certain of the rails a, a, herein the top and bottom rails. Such supports herein are constituted by brackets. Around the said vertical glass rods the yarns change direction after leaving the guiding, clearing, etc., devices aforesaid. From said vertical glass rods the yarns proceed to the winding mechanism. In order to prevent the yarns from rubbing against rough iron parts after leaving the combined thread-guides, clearers, etc., and to prevent the numerous yarns to be applied thereto, without inter-fer ing with the other cops or bobbins, or with.

from colliding with one-another, they are led around the glass rods d just mentioned.

Each of the horizontal rails or channelbars a, with the exception of the top one, supports a seriesof bobbin or copcarriers, and each thereof with the exception of the bottom one, supports a series of the combined guides, clearers, and tension-devices. The said'devices usually are termed valves or thread-valves in the art.

The bobbin or cop-carriers and. also the combined guides, clearers and tension devices, and the construction thereof, are fully presented in the applications hereinbefore mentioned, and the Letters Patent granted thereon to which reference may be made. It will be sufiicient herein to refer brieflyto' the cop-carriers as comprising each a baseo and a series of bobbin or cop-receiving spindles f. See more particularly Fig. 3. 'lhe'said spindles are hinged or pivoted on said base so that a spindle may be swung downward and outward into position to enable'an empty cop-tube or bobbin to be removed therefrom and a full cop or bobbin the unwinding yarn or thread as it circles about the cop or bobbin'from which it is unwinding. The base 0 of each cop-carrier rests upon the upper surface of the support ing rail or channel-bar a therefor, and is secured in place upon the said railfor channel-bar, In practice, when the cops are placed on the spindles f the inner'end of the yarn 'or thread of one cop is connected to the outer end of the yarn: or thread of the next cop in the manner explained in the applica-v tions aforesaid. The combined guide, clearer and tension device'through which the unwinding yarn or thread passes is located immediately above the inner ends of.

the cops upon the spindles f of a given cop carrier. The said combined guide, clearer and tension device is mounted upon the rail or channel-bar a; next above that on which the cop-carrier is mounted. It comprises essentially a seat or guide 79 consisting of a glass ring, and a glass plate or disk m which rests upon the top of the said ring. The yarn or thread unwinding from one of the bobbins or cops of thecop-carrier: below passes up through the bore of the ring 39 and then turns, passing outward between the ring and the plate or disk, to and around the adjacent vertical glass rod (Z.' The plate or disk rests by gravity upon. the yarn, the friction due to the passage of the yarn through'the bore of the ring, and to the bending of the yarn or thread nearly at right angles over the ring, as well as to the passage of the yarn or thread between the surfaces of the ring and plate or disk, imparting the required tension to the yarn or thread. Other appurtenances are as shown and described in the applications. aforesaid. What is claimed as'the invention is, The improved frame or creel for Warping machines, etc., having converging opposite sides, each side composed of longitudinallyextending horizontal rails and uprights supporting said rails vertically one above the other, said rails anduprights arranged to form a number of compartments in each side, a plurality of upright bobbinor copcarriers mounted onsaid horizontal rails in each compartment, each of said carriers adapted to support a group of bobbins or cops side by side in upright position, unwinding-guides supported by said horizon tal rails above the said carriers, the inter" mediate horizontal rails supporting both .a seriesof the said bobbin or cop carriers" and the series of guides pertainingto the next lower series of bobbin or cop carriers, outstanding supports d, d, mounted on-said rails, and vertical rods cl, cl, carried by the said supports and around which theyarns change direction after leaving the saidguides.
